We just bought the Echo PAS-2600 ( I believe that's the name?) Its the highest cc split boom engine they had. Anyway we bought both he articulating hedger and the power edger for it. My problem is this, when we start it up and you hit the gas it bawgs. It does this for about 5 minutes or so straight you have to keep toying with the throttle to keep it running and get the blade spinning. Its the same type of thing if you put your stick edger on the dirt then hit the gas, it bawgs the same way. Is this normal? I figure the strain from the split portion of the boom could be doing it but not too sure if this is normal or not. After operation it for a couple of minutes at full throttle its fine. It does the same thing with the articulating hedger blade on it?? What gives?
